Dog Quality of Life Calculator
This calculator helps owners of ill or elderly dogs track quality of life over time. It covers pain, appetite, hydration, hygiene, happiness, mobility and the proportion of good versus difficult days. It is a discussion aid, not a diagnosis or a euthanasia decision-maker. Use it to observe trends and prepare questions for your veterinarian.
Quality of Life Assessment
Rate each category from 0 (severe problem) to 5 (excellent). Be honest—this tool is for your own observation and veterinary discussion.
Understanding the Categories
Pain
Signs of pain include panting at rest, restlessness, reluctance to move, whimpering, hiding, aggression when touched, or a hunched posture. Chronic pain can be subtle. If you suspect pain, ask your veterinarian about a pain trial—response to medication can confirm pain even when signs are ambiguous.
Appetite and Hydration
Refusing food or water, eating less than usual, or only eating with encouragement are all significant changes. Persistent changes warrant a veterinary visit, as they may signal nausea, dental pain, organ disease or other treatable conditions.
Hygiene
Can your dog stay clean and dry? Soiling themselves, urine scald, or persistent wetness are quality-of-life concerns, especially in dogs with mobility limitations.
Happiness and Engagement
Does your dog still respond to favourite people, toys, walks or food? Loss of interest in things that used to bring joy—veterinarians sometimes call this “loss of housebroken behaviour” or “loss of joy”—is an important marker.
Mobility
Difficulty rising, stumbling, falling, or reluctance to walk are signs that mobility is declining. Pain management, physical therapy, harnesses and environmental modifications can help.
Good Days vs Bad Days
Track whether good days are becoming fewer and bad days more frequent. A trend of more difficult days, even if some are still good, is important information for your veterinarian.
How to Use This Tool Over Time
Repeat the assessment weekly or monthly. Write down the date and score each time. The trend matters more than any single number. A declining trend is a signal to schedule a veterinary conversation—not necessarily a decision, but a prompt to seek guidance.
Bring your notes to your veterinarian. They can interpret changes in the context of your dog’s diagnosis, prognosis and available treatments, and help you think through options with compassion and clarity.
This tool does not provide a diagnosis and does not make euthanasia decisions. If your dog is in uncontrolled pain or shows a concerning decline, contact your veterinarian promptly.
